About

The e⁺e⁻ Alliance tries to systematically collecting and documenting all available LEP samples and analysis artifacts in an easily accessible format for all alliance contributors to accelerate cross-checks, reproducibility, and new studies from recent theoretical development and experimental technique advancement. The Alliance reanalyzes archived ALEPH LEP data across √s ≈ 91–209 GeV to deliver modern QCD and correlation studies. Published highlights include precision jet-energy spectra and substructure at the Z pole, two-particle correlations at 91 GeV, and evidence of long-range near-side correlations at 183–209 GeV. Ongoing analysis notes extend this program with thrust and energy–energy correlator measurements at 91 GeV and broader two-particle correlation studies using contemporary event-shape and jet-substructure techniques with both archived ALEPH and DELPHI samples. In parallel, we are trying
